With 48fps, as by my understanding, it has the potential to increase sfx budgets considerably, not to mention increases in rendering times (editing, grading etc), storage, bandwidth, potentially even computer and network infrastructure. Some (not all) of those issues are also a consideration when you increase resolution, though the public seems to understand the benefit of higher resolution more than increased frame rate.
Maybe it will be, then, if 48fps continues to be used, that only tent-pole productions will do so --films like
The Hobbit trilogy or the
Avatar sequels (not that the
Avatar sequels will be --I have no idea. Just saying that sort of movie). But big films like those, perhaps big 3D films like those, which a studio can be confident will be profitable.
Maybe, too, I wonder, folks who don't care for 3D might be the among the same folks who will shun HFR? 'Cause maybe it's those of who do like well done 3D who will be more inclined to also appreciate HFR.
Anyway, I for one am ready for 3D, 4K(and +), and HFR spectaculars!
The local AMC multiplex is showing
Interstellar in 4K, and I must say: it looked spectacular
without 3D
or HFR. But, maybe it would have been even more spectacular with the addition of either one or both of those...?
Last, do you know if some/majority of cinemas are charging more for a ticket in Atmos, handling it the same way as 3d? ... or are they using it as their competitive advantage. Same price, better product.
I know you didn't ask me. And I know I can't answer it like APE or others can. [I missed C&C's and APE's answer before posting.

] But the local theater that recently remodeled its flagship screen to, among other things, equip it with Atmos, hasn't, as far as I can tell or figure, explicitly added or said that it's charging more for Atmos. However, the "UltraScreen" -that's what they call it- I think has always cost a bit of a premium. With the most recent remodel, they actually reduced the number of seats and installed recliners. Well,
here's how they advertise it. What I notice is that no where do they say that the Atmos provided will cost X dollars premium. And I never noticed them advertising such a premium surcharge explicitly as a cost of Atmos. However, an UltraScreen ticket does cost a premium. And I'm guessing that almost must be to help recoup the costs of installing Atmos. But that probably also goes for covering the cost of significantly fewer seats, more expensive chairs, etc. And of course they're clearly going for the "premium experience" sell, overall. I suppose DLX stands for "deluxe."
Not assuming that the example of what one company is doing is representative, of course.
There has been an interesting thread (or more) discussing the trend of theaters moving toward the "premium experience."
